The total data volume of the original dataset is ~500TB, which has traditionally been stored as ~150,000 individual CF/NetCDF files on disk or magnetic tape made available through the NCAR Climate Data Gateway for download or via web services. The summary of time series processing is output in Output 7.1.1. The directories in $DIN_LOC_ROOT should generally be group writable, so the directory can be shared among multiple users. The coupled CICE model requires a minimum of two files to run. ; CESM is a fully-coupled, community, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and … However, on supported machines (and some non-supported machines), data already exists in the default local filesystem input data area as specified by $ DIN_LOC_ROOT (see below). To join the 'cesm_input-data' project, log into SUPR (https://supr.snic.se/) and click the 'View and Manage Projects' button, the request membership to the snic2014-5-61 project. NCAR has copied a subset (currently ~70 TB) of CESM LENS data to Amazon S3 as part of the AWS Public Datasets Program. NCAR and collaborators have developed additional packages to support CESM input data pre-processing, output data post-processing, ... CESM Project. For supported machines, this variable is preset. dataset(s) names that are different than the names in $DIN_LOC_ROOT, The finite volume is generally associated with atmosphere and land models but the data ocean and data ice models are also supported on that grid. If you experience problems such as checkout_externals hanging, run: Permanently accepting the certificate when prompted, then retry the CESM download starting over at the top of these instructions. then the build can proceed. input data to reside on local disk. The Parallel Input/Output libraries or “PIO” are used within the CESM for more efficient reading and writing. CESM … downloading input data. This prevents these files from being accidentally modified or deleted. Renewal requests also require CESM working group co-chair and CSEG approval. This CESM shared input data directory is located at /work/n02/shared/cesm/inputdata/. in /user/home/newdata with the following command: then incorporate the new dataset(s) directly into the appropriate Details regarding the CESM checkout process are available in the CESM GitHub repo README , to see more details regarding the checkout_externals script from the command line, type: To confirm a successful download of all components, you can run checkout_externals with the status flag to show the status of the externals: If there were problems obtaining an external, you might see something like: This might happen if there was an unexpected interruption while downloading. populated with user-specified input datasets.

If they are not, then the scripts will automatically pull the necessary associated input files from the CESM svn repository and place them in the input directory. Datasets can be downloaded on a case by case basis as needed and CESM provides tools to check and download input data automatically. $DIN_LOC_ROOT. With valid git and svn clients installed on the machine where CESM will be built and run, the user may download the latest development or production release by running one of the following commands: * You should use the most recent version of the model that is available unless you are trying to replicate previous results or create a branch run from a previous experiment. Datasets can be downloaded on a case by case basis as needed and CESM provides tools to check and download input data automatically. About CESM2. If a problem was encountered during checkout_externals, which may happen with an older version of the svn client software, it may appear to have downloaded successfully, but in fact only a partial checkout has occurred. Example below showing a clean status output for all externals after running checkout_externals with the status flag, note there are no characters in the first two columns of output. The heading (e.g. The namelist input file (pop2_in and user_nl_pop2) will need to be changed as well. NB before building CESM, the input, archive and scratch directories must exist. 5. Buildconf/$component.input_data_list files. can independently verify that the required data is present locally by the build script will abort and the files that are missing will be You The dataset includes net all-sky and clear-sky radiative fluxes at both the top of the atmosphere and surface. For supported machines, this variable is preset. Data included here include model input data (used to run the biogeochemical testbed), and annually averaged model output (analyzed in Wieder et al. 2013). Use the links below to view other CESM release instructions. First try rerunning ./manage_externals/checkout_externals If there is still a problem, try running with logging turned on: Check the manage_externals.log file to see what errors are reported.

The latest CESM production release is CESM2.1.3. If any of the required Access to the code requires both git and Subversion client software in place that is compatible with GitHub and our Subversion server software. For example, if the land/ocean mask is changed, the input template file containing new indices for diagnostic transport calculations will need to be changed. The files in the subdirectories of $DIN_LOC_ROOT should be write-protected. To run CESM or RASM with VIC, several sets of input data are necessary: Input Configuration File: This file lists the individual input files used by the CESM driver. CESM input data are available through a separate Subversion input data repository. Input datasets are needed to run the model. The default format for all reads and writes of files in CESM is now pio, but this can be changed to binary or netCDF through the namelist variable, restart_format. They are designed to be useful to a variety of researchers in the CESM community. See the input data variables. If all required data sets are found on local disk, if the required data files for the case exist on local disk in the Box 3000, Boulder, CO 80307-3000 A local input data directory should exist on the local disk, and it also needs to be set in the CESM scripts via the variable $DIN_LOC_ROOT. For what to expect when interacting with a Subversion repository, see listed. machines), data already exists in the default local filesystem input data The source code, build and run scripts can be downloaded as described in the CESM 2.1.0 quick guide. the input data server: Required data files not on local disk will be downloaded through Input data is handled by the build process as follows: The buildnml scripts in Buildconf/i create listings of CESMwith these components. However, on supported machines (and some non-supported machines), data already It is possible for users to download the data using svn subcommands directly, but use of the check_input_data script is highly recommended to ensure that only the required datasets are downloaded. CICE Input Data¶. area as specified by $DIN_LOC_ROOT (see below). All runs. the presence of the required input data files in the root directory CESM can be configured with many combinations of its components (CAM, CLM, POP, CICE, …) some of which may be ‘data’ components, which merely read in data from some external source and pass it to the other, active, components to use. When users build their case, the input directory will be probed to check if the associated input files are available. proc cesm data=mycas.sales outfor=mycas.nextyear; id date interval=month; forecast _numeric_ / lead=12 method=simple; run; The preceding statements generate forecasts for every numeric variable in the input data table mycas.sales for the next 12 months and store these forecasts in the output data table mycas.nextYear.

If you want to use new user-created dataset(s) and give these A local input data directory should exist on the local disk, and it also needs to be set in the CESM scripts via the variable $DIN_LOC_ROOT. we recommend using the script link_dirtree in the directory -data_reference: Full reference for the dataset if available-data_doi: If doi of data exists-climo_years: Year 1-year N of the climatological averaging period.-data_mods: Any special substantive (non resolution) modifications that were made to the input data set purely for the purpose of using it in CESM. The CESM project is supported primarily by the National Science Foundation (NSF).Administration of the CESM is maintained by the Climate and Global Dynamics Laboratory (CGD) at the National Center for Atmospheric Research (NCAR). There are separate versions of this documentation for each maintained CESM release. ; kmt_file is a binary or netcdf file containing land mask information. A local input data directory should exist on the local disk, and it also needs to be set in the CESM scripts via the variable $DIN_LOC_ROOT. If the required data is not found on local disk in $DIN_LOC_ROOT, then the data will be downloaded automatically by the scripts or it can be downloaded by the user by invoking check_input_data with the --download command argument. You will still be required to input your CESM SVN developer's credentials in order to access the form. All active and data components use input datasets. Currently, our Subversion server software is at version 1.8.17. The YCRC staff are only people who can add to that directory, so if your build fails due to missing inputdata, send your create_newcase line to Kaylea (kaylea.nelson@yale.edu) and she will download that data for you. interaction with the Subversion input data server. The script $CASEROOT/check_input_data determines Earth System Community Modeling Portal CESM repository. a local copy of $DIN_LOC_ROOT which can then be The components influence each other only through the coupler. For more information or to download open source tools, visit Subversion and git downloads. placed in the appropriate subdirectory of $DIN_LOC_ROOT. When contacting the Subversion server for the first time, you may need to accept an authentication certification. To reduce the amount of data duplication on the cluster, we keep one centralized repository of CESM input data. It is recommended that all users of a given filesystem share the same $DIN_LOC_ROOT directory. In addition, several input template files may need to be changed. To use this script, use the -h optiion For example, you can - Revision 34301: /trunk/inputdata.. MaxTSIInput; atm/ ccsm4_init/ cesm2_init/ cpl/ dx7/ filelist; glc/ hiresFiles; ice/ import/ lnd/ ocn/ rof/ share/ template.readme Please note that there is a shared input directory which contains the largest and more popular input data files, but this directory is read only. Each release includes the complete collection of component model source code, documentation, and input data. $CCSMROOT/scripts. If you want to download the input data manually you should do it before you build CESM. Data are provided on the CESM hybrid-sigma grid for comparison with CESM simulations. Files are available for a 20th Century simulation (1951-2005) and three concomitant Representative Concentration Pathway (RCP) future scenarios (RCP4.5, RCP6.0 and RCP8.5) spanning 2006-2100.\n\nNOTE: There are no bias-corrected data for RCP2.6, due to corrupted data caused by a model bug in CESM.\n\nNote to Microsoft Windows users: The executable metgrid.exe, which is required to … There are several modes of assimilating observations in this context. If you want the input data files to stick around for future CESM runs, you may want to consider changing the path to somewhere in your project directory to avoid the scratch purge. grid_file is a binary or netcdf file containing grid information such as the latitude, longitude, grid cell area, etc. CESM is a fully-coupled, community, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states. Administration of the CESM is maintained by the Climate and Global Dynamics Laboratory (CGD) at the National Center for Atmospheric Research (NCAR). First, let's take a look at some of the ingredients that go into the control run. Do not attempt to download the whole input data repository, it is currently over 20 TB. - Revision 33790: /trunk/inputdata/cesm2_init/f.e20.FW1850.f09_f09_mg17.295_v2/0021-01-01.. f.e20.FW1850.f09_f09_mg17.295_v2.cam.i.0021-01-01-00000.nc Starting with CESM2, releases are available through a public GitHub repository. You will need access to the command line clients, git (v1.8 or greater) and svn (v1.8 or greater but less than v1.11). The CESM project is supported primarily by the National Science Foundation (NSF). provides the capability for downloading them to the $DIN_LOC_ROOT required component input datasets in the CESM version 2.0.1 (the original public-release version of CESM2, and scientifically identical to public version 2.1.0) was run on a nominal 1-degree finite-volume horizontal grid for 30 years to assess the model's ability to represent atmospheric rivers (extreme precipitation events) and their related weather patterns. If any of the required input data sets are not found, The latest CESM development release is CESM2.2.0. A local disk Input datasets are usually on the same grid but in some cases, they can be interpolated from regular lon/lat grids in the data models. The sign convention is the same as CESM's: shortwave fluxes are positive downward, and longwave fluxes are positive upward.
